Any way to test out compiled scripts in physical iPad without a developer account?browsing

I'm loving Pythonista. It is exactly what I would consider a nice way to develop some simple apps.
But when I tried to compile it in Xcode and tried to run it, since I still don't have a developer account, I can only try it in the virtual simulator.
In there, some stuff did not showed up exactly as it shows when I run the script in Pythonista.
For example, then I set the size of the font for a TextView item with my_item.font('fontname',38), the font, once compiled, doesn't appear in size 38 (it appears smaller).
Since I don't know if this is a problem of the virtual simulator, I would like to try it running in the iPad itself.
But I'm not willing to invest in a full year developer fee if it proves to be a problem that also happens in the real-life environment (I'm not a full time programmer. I'm just a freelance designer that likes to code).
Is there any way for me to install a compiled app in my iPad to test it in real-world conditions?

Does the font show up correctly when you simply run your script from the Pythonista app? It could be that you're using a font that isn't preinstalled on iOS – the app contains a few extra fonts that aren't included in the Xcode project template (mostly the different monospace fonts you can use for the editor – iOS only has Courier by default)...

Thank you for the answers.
In fact I was not using a system font. I was using a font that I had added with AnyFont.
Using a system font (I tried with Gill-Sans) it previewed fine in the simulator.
However, I would also like to test out how my apps behave with a bluetooth keyboard and I can't because whenever I click in a TextField, the soft-keyboard shows up. As soon as I retract it, the TextField becomes inactive.
So, the only way to really test real-world scenarios is running the app in the physical iPad.
I really don't want to jailbreak it (required, for the method that the tutorial shows).
I already found a way to create an .ipa file but when I try to install it in my iPad through iTunes, to test it out, it appears darkened and, when I click it in my iPad, it show "Installing..." and never really executes.
